GB Door Camera Unit
Installation of the Door Unit
1. Choose a suitable place for mounting and attach the hood.
2. Pull the power supply cable through the mounting opening and connect it to the terminal at the
rear of the door camera unit.
3. Attach the connected door unit to the covering hood using the enclosed screws.
Door unit on plaster – apply a layer of silicone between the wall and the door unit to prevent humidity
from getting under the door unit. The silicone should be applied on the top and the sides. The bottom
side must be left open to allow humid air from exiting the space under the door unit.
Door unit under plaster – it is recommended to fill out the space between the mounting box (not inclu-
ded) and the wall with mounting foam to insulate the unit from the surrounding wall.
Parameters of Interlinking Cables
For distances under 20 m, use a quality UTP CAT.5 cable (optimally CAT.6).
For distances over 20 m, we recommend a SYKFY 5 × 2 × 0.5 or 10 × 2 × 0.5 cable. To achieve higher
diameter, cables can be doubled or tripled.
The resulting diameter of the conductors is as shown in the table:
Conductor core diameter [mm]
Distance [m]
In the basic implementation, a coaxial cable is not required. Such a cable is only recommended for
distances over 100 m.
For long ground cabling, you can use a telecommunication cable of category TCEPKPFLE.
Device Maintenance
The door unit requires little maintenance. It is recommended to occasionally wipe the device down with
a moistened cloth when it becomes dirty.
Warning! Before cleaning, the device must be disconnected from power supply!
Safety Warnings
• Do not disassemble the door unit.
• If sunlight shines directly into the lens of the door unit, the image on the videomonitor may
become illegible.
• Do not subject the device to vibrations or falls.
FAQ
The lens steams up
This occurs mainly during cold weather, where condensation occurs due to the temperature difference
between the wall and the door unit itself. If water condenses on the lens, we recommend thoroughly
drying the door unit and adjusting the installation.
Spontaneous ringing
Spontaneous ringing is caused by moisture entering the camera. Water short-circuits the contacts on
the lock switch and the device will start ringing on its own. We recommend dismounting the door unit,
drying it thoroughly and spraying it with water repellent for electronics.
